Claims (8)

1. Способ получения фторированной сульфокислоты, включающий стадии контактирования фторированного сульфонилфторида с водой в присутствии основного вещества, отделения от реакционной среды смеси, содержащей (соответствующую фторированную сульфокислоту в виде соли основного вещества и фтористоводородную кислоту в виде соли основного вещества, и выделения целевого продукта, отличающийся тем, что в качестве основного вещества используют третичный амин, инертный в отношении образования амида в условиях реакции.1. A method of producing fluorinated sulfonic acid, comprising the steps of contacting fluorinated sulfonyl fluoride with water in the presence of a basic substance, separating a mixture containing the corresponding fluorinated sulfonic acid as the salt of the basic substance and hydrofluoric acid as the salt of the basic substance, and isolating the target product, different by using a tertiary amine as the base material, which is inert with respect to the formation of amide under the reaction conditions. 2.
